Cannot send a content-body with this verb-type.

[DeniseDornell]

Client.Checkout.GetOrder(orderId).Result and Client.OrderManagement.GetOrder(orderId).Result is just awaiting without any result

It works if I create a own request with HttpClient

[martingust]

@DeniseDornell Do you get any errors?

You can try inspect to see the request and response JSON? You can implement a custom JSON serializer in order to do that https://github.com/klarna/kco_rest_dotnet/blob/v3.0/Klarna.Rest/Klarna.Rest.Core.Examples/CustomJsonSerializer.cs

Also what happens if you use async/await instead of .Result? Do you get any better error?

#35

[alexions]

Thanks to the Guillermo

With his help we found an issue (I suppose for the older versions of .NET Core) when sending the GET requests.

HTTP 1.1. Specification says, that GET request should not have a body (but it can have), but the reality, you will get a verb-type exception when sending the GET with a body inside.

So the fix allows to set null when no body data instead of string.Empty
